Current release

Pre-compiled (provisional) executables are available for Windows
(MrBayes-3.2.7-WIN.zip).
These are, however, serial versions compiled without the Beagle library. The
serial version works well for smaller analyses but if you plan to
run large analyses using many parallel chains, you should use the
MPI version instead. Refer to the User
Manual, and the INSTALL
document on GitHub for help with installation of the program.

MrBayes may also be installed through the Homebrew package
manager on macOS, Linux, and Windows Subsystem for Linux (WSL).
Please see the INSTALL
document for instructions.
